Roeland Nusse
Virginia and Daniel K. Ludwig Professor of Cancer Research
Current Research and Scholarly InterestsOur laboratory studies Wnt signaling in development and disease. We found recently that Wnt proteins are unusual growth factors, because they are lipid-modified. We discovered that Wnt proteins promote the proliferation of stem cells of various origins. Current work is directed at understanding how Wnt signals lead to the proliferation of stem cells and on understanding Wnt signaling during repair and regeneration after tissue injury.

Fridah Nyakundi
Ph.D. Student in Environment and Resources, admitted Autumn 2021
BioI am a Ph.D. candidate in Environment and Resources at Stanford University’s Emmett Interdisciplinary Program in Environment and Resources (E-IPER). My research sits at the intersection of environmental and natural resource economics and land system science, applying remote sensing and economic methods to understand how natural resource use shapes livelihoods and ecosystems in low- and middle-income countries. Currently, my doctoral work focuses on the risks and decision-making strategies in aquaculture systems, with a case study on Nile Tilapia cage farming in Lake Victoria. While aquaculture is the subject of my current research, my broader interests span natural resource management (NRM) economics, agriculture and environmental economics, land system science, and food systems resilience. Before graduate school, I spent five years at the International Centre for Tropical Agriculture (CIAT), supporting the design and execution of large-scale impact assessments and leading the setup of data systems for the Africa research team. I have been a fellow at Environment for Development (EfD) Kenya since 2017, contributing to applied water and resource economics research.

Dáibhid Ó Maoiléidigh, PhD
Assistant Professor of Otolaryngology - Head & Neck Surgery (OHNS)
Current Research and Scholarly InterestsThe Ó Maoiléidigh group employs mathematical and computational approaches to better understand normal hearing and hearing impairment. Because complete restoration of auditory function by artificial devices or regenerative treatments will only be possible when experiments and computational modeling align, we work closely with experimental laboratories. Our goal is to understand contemporary experimental observations, to make experimentally testable predictions, and to motivate new experiments. We are pursuing several projects.
Hair-Bundle Mechanics
Auditory and balance organs rely on hair cells to convert mechanical vibrations into electrical signals for transmission to the brain. In response to the quietest sounds we can hear, the hair cell's mechanical sensor, the hair bundle, moves by less than one-billionth of a meter. To determine how this astounding sensitivity is possible, we construct computational models of hair-bundle mechanics. By comparing models with experimental observations, we are learning how a hair bundle's geometry, material properties, and ability to move spontaneously determine its function.
Cochlear Mechanics
The cochlea contains the auditory organ that houses the sensory hair cells in mammals. Vibrations in the cochlea arising from sound are amplified more than a thousandfold by the ear's active process. New experimental techniques have additionally revealed that the cochlea vibrates in a complex manner in response to sound. We use computational models to interpret these observations and to make hypotheses about how the cochlea works. -

Lucy Erin O'Brien
Associate Professor of Molecular and Cellular Physiology
Current Research and Scholarly InterestsMany adult organs tune their functional capacity to variable levels of physiologic demand. Adaptive organ resizing breaks the allometry of the body plan that was established during development, suggesting that it occurs through different mechanisms. Emerging evidence points to stem cells as key players in these mechanisms. We use the Drosophila midgut, a stem-cell based organ analogous to the vertebrate small intestine, as a simple model to uncover the rules that govern adaptive remodeling.
